Summary: The tribological performance of a copper alloy engine bearing under oil lubrication, seawater corrosion, and dry sliding wear was investigated. Three different PI/PAI/EP coatings with varying amounts of Ce2O3 were designed and prepared using a liquid spraying process. The tribological properties of these coatings were tested under different working conditions. The results showed that the hardness of the coating decreased with the addition of Ce2O3 due to the agglomeration of Ce2O3. The wear amount of the coating initially increased and then decreased with the increase of Ce2O3 content under dry sliding wear. Under seawater corrosion, the wear resistance of the coating decreased with the increase of Ce2O3 content. The coating with 1.5 wt% Ce2O3 exhibited the best wear resistance. Under oil lubrication conditions, the coating showed stable frictional coefficient and good lubrication and protection effect of the lubricating oil film.

Summary: This research investigates the wear characteristics and wear resistance of composite powder coatings containing different chromium concentrations, deposited by supersonic flame jet. It was found that with increasing chromium concentrations, wear intensity decreases and reaches minimal values at 16% Cr. Coatings with 20% Cr exhibit increased wear intensity due to the absence of B and Si components, resulting in a lack of inter-metallic structures with high hardness and wear resistance.

Summary: This study investigates the wear mechanisms of a used, soot-containing oil drained from an engine test. Previous studies often used fresh oils with added carbon black as a soot mimic, which may not accurately represent the oxidation pathways in engines. The research applies tribometer tests and surface analysis techniques to evaluate the wear performance of engine-drained oil on AISI 52100 steel. The results indicate the corrosive-abrasive wear mechanism involving anti-wear film formation and subsequent removal by soot abrasion.

Summary: Promoting the martensitic transformation through optimum microalloying with Fe and/or Mn has been proven to effectively enhance the wear resistance of Cu50Zr50 at% shape memory alloy (SMA). Partial replacement of Cu by up to 1 at% Fe and Mn is of interest as it results in a significant decrease in stacking fault energy and leads to the highest martensitic transformation and lowest specific wear-rate.

Summary: The influence of laser modes and power on the tribological behavior of additively manufactured Inconel 718 alloy using the DED process was studied. The samples were fabricated with CW and PW laser modes at different laser powers. The results showed that the hardness and modulus of the samples increased with laser power due to increased densification and hardening secondary phase. The samples exhibited low wear rates and the dominant wear mechanism was three-body abrasive wear followed by localized and discrete adhesion wear mechanism.

Summary: In this study, a elasto-plastic constitutive model of friction incorporating the concept of superloading surface was developed based on the subloading friction model. The proposed model achieves a smooth transition of friction by describing the evolution rule of structure, treating the state with static friction coefficient larger than kinetic friction coefficient as the bulkiness of structure. The positive definiteness of the plastic multiplier, loading condition, and material parameters were derived, and the validity of the proposed model in accordance with the subloading-friction model was confirmed through a stick-slip simulation of a mass-spring system.

Summary: This paper investigates the influence of preparation strategies on the lubrication properties of surface textures. Three laser scanning strategies are proposed to achieve a sinusoidal textured surface, and the evolution of surface structure and chemical composition is discussed. The findings show that ridge structures enhance anti-wear properties but also increase the friction coefficient. However, the oil cover preparation method prevents the formation of ridges and improves wettability.

Summary: This study investigates various methods to improve the machinability efficiency of Inconel 718 alloy while considering their effect on microstructural properties. The results show that hot+PMQL, hot+SiCNMQL, and hot+Al2O3-NMQL contribute significantly to the improvement of machinability characteristics. The EBSD analysis also reveals that a limited area is affected by heat in the hot machining environment and that the removal of the heated layer during milling process helps preserve the microstructure.

Summary: This study presents a systematic approach to generating control signals for a tactile simulator that simulate the touch of textile fabrics. By using a friction modulation tactile surface and acquiring forces from real surfaces with artificial finger mimicking fingerprints, control signals are generated and processed in the frequency domain before sending them to the tactile stimulator. The study focuses on the potential benefits of incorporating fingerprint information in fabric simulations to achieve a more realistic tactile perception. A sensory analysis with 36 participants using the generated control signals showed better discrimination without fingerprint information.
